Grouchy John isn't very grouchy. I'm not sure if that should be a complaint or a compliment, but it is a great experience. I had Grouchy John's at UNLV and not only is it the BEST coffee on campus, but it is also the nicest food truck. My only complaint is that the coffee sizes aren't big enough for me...BUT, if you bring your own coffee container they'll hook you up with the right size!
